I am currently reading computer science literature in data privacy. However, I encountered the following sentence that seems confusing to me
In other words, we ask for a refinement of Dalenius's goal: that nothing about an individual should be learnable from a dataset that cannot be learned from the same dataset but with that individual's data removed.
I understand "that nothing ... from a dataset", but not sure about the meaning of modifier of dataset. From the context of the text, it seems that the sentence should mean "with and without individual's data makes no difference".
However, I think it is still necessary to fully understand this sentence because it uncovers some design principle of data privacy.
Could someone help me? Thank you in advance!
